The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.

Perfect sound to go with the perfect fit
JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.

The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.

Enjoy enhanced, custom-fit sound
This Stealthbox® enclosure fits 2004-2007 Chevrolet Colorado and GMC Canyon Crew Cab trucks. It goes in front of and beneath the center of the back seat. This Stealthbox® includes one down-firing W3v3 10" 2-ohm subwoofer from JL Audio. Please check with us before purchasing by using the vehicle selector on our site, or calling a Sales Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as low. You should be able to install this enclosure if you have any experience with car audio.

Note: You'll sacrifice the last "click" of seat adjustment in front bench-seat equipped models. This Stealthbox® enclosure will not fit in Regular Cab or Extended Cab Colorado/Canyon models.

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Features

Construction: Stealthboxes are hand-crafted from fiberglass
and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of
enclosure rigidity and dimensional stability not possible with other enclosure
materials, allowing wall thickness to be reduced compared to a typical wood
enclosure. This gives you more interior box volume for a given external volume.
Fiberglass and AMC materials are very strong and can be molded into very complex
shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly
into tight spots and minimize intrusion into your vehicle's useful space. Each
Stealthbox is laminated, ground, joined, and finished by hand in the USA.
Proprietary techniques and materials developed by JL Audio through years of
fiberglass manufacturing experience ensure consistent quality and performance.

Woofer: One 10" JL Audio W3v3-2 subwoofer is loaded in this
sealed enclosure and wired as a 2Ω load at the enclosure's 5-way post speaker
terminal.

Dynamic Motor Analysis (DMA): DMA is JL Audio's
proprietary method aimed at improving dynamic motor behavior. As a result of
DMA optimization, W3v3 motors remain linear in motor force over a very long
range of excursion, and also maintain a highly stable fixed magnetic field
in the gap over a wide power range. The result is vastly reduced distortion,
faithfully reproduced transients, and tight, clean, articulate bass.

Vented Reinforcement Collar (VRC): The Vented
Reinforcement Collar is a composite structure that addresses two issues
related to reliability. By reinforcing the critical junction between the
cone, voice coil and spider, the VRC greatly reduces failures due to glue
breakdown or material weaknesses. It does this by greatly increasing
adhesive contact area and providing stress relief to the spider material at
excursion extremes. the VRC also feature slots that facilitate air flow
directly onto the voice coil windings to reduce thermal compression effects
and enhances reliability.

Spider/Lead Wire Assembly: The W3v3 features a unique
spider, coil and terminal subassembly which is assembled prior to
installation in the speaker frame for optimum alignment and glue-joint
integrity. The spider is insert-molded into a composite carrier tray which
also incorporates the terminal assembly and lead wire strain relief features
for enhanced reliability and optimal alignment of parts. The flying lead
wires are carefully controlled and strain-relieved without resorting to
woven-in lead wires, which can degrade spider performance.

Elevated Frame Cooling: The elevated frame design of
the W3v3 delivers high-velocity air flow through slots directly above the
top plate to the voice coil of the speaker. This not only enhances power
handling, but also sound quality by minimizing dynamic parameter shifts and
power compression.

Surround Stress Relief: By creating a radiused feature
on the edge of the cone, stress is relieved from the surround material at
maximum forward excursion, resulting in longer life and more consistent
surround behavior.

Great Buy

Written By David, Lucedale, MS on Saturday, June 11, 2011

When I first bought this I wasn't sure if it could produce the amount of bass i was hoping for. But I always heard great things from JL, and this is the first JL product I've purchased. I must say for the small sized box, this 10 beats. I installed a 500 watt 2 ohm alpine amp on it, and it sounds amazing. I was highly impressed by the deep, rich bass it produced :) I do believe this was worth the money. Just wish i waited and got that 10% discount. lol

Worth the money

Written By Shawn, Seattle Washington on Sunday, March 01, 2009

I have to admit I had a lot of hesitation and a lot of questions if this enclosure would give me enough bass and how good it would sound. I mean it is a very small enclosure and only 1 10" w3? Well I just had it installed and I have had 15's, 8's, 12's and I have to say that this box with the right power will give you all the bass you need. If you are looking for window breaking bass do not bother but if you appreciate clean, percise hitting bass with enough flex to play rap, rock, jazz, and many other kinds of music than it is worth the money. Now I do have it hooked up with 300rms power at 4ohm which is its peak rms power and have chosen very high quaility equipment to power this sub. If you are looking to run it with cheap power then I can not vouch for how it will sound. I am running it with a 5 channel amp, 4 guage wire, directional RCA's, Kenwood Excelon that has 4 volt output just to give you an idea of why it sounds good. I too think that the enclosure is a bit high in price but a lot of engineering had to go into this small box to make it sound so good. Good luck and happy listening:-)

great speaker. really nice bass. this speaker can rip. great sound for one sub. if you cant hook up your amp to the factory stereo just tie into the pink wire from the 4wd button right above stereo. factory stereo has no remote. use that wire. enjoy
